The demographic characteristics of the two groups were compared using an independent t-test. The effects of the course were statistically analyzed by comparing the pre- and post-test scores of the groups with repeated-measures analysis of variance (ANOVA). Cohen’s
effect-size evaluation was performed to reveal increases in the mean. Further analysis of each category involved comparisons with repeated-measures ANOVAs. Values are presented as means?standard deviations. AP-value below 0.05 was considered to indicate statistical
significance
